You!
This appeared as the million dollar question on the game show “Who wants to be a Millionaire”.

Just let me say that 1975 is when I got started in this and my answer is based on almost 35 years of Interest in Observing the visible Universe from California near Disneyland.

Mean distance from the sun is 92,957,200 miles

93 million miles
On average. This number actually varies by both the seasons of the year, and by the varying nature of earth's orbit itself. It's not always elliptical, but rhythmically gets closer to a circular orbit then back to an ellipse.
93 million miles
My favorite Astronomy Prof in college, of whom I was his class assistant, would always tell the Gen Ed classes that:

"the sun is roughly 93 million MILES and 150 Million KILO METERS so for an easy way to remember the distance, especially since Americans refuse to shift to metrics, is to remember its "About" 100 million then you can remember it is half again as much for Kilometers and I will take that answer on the test."

So I have always remember the rough distance because basically Freshmen are Stupid...
And full of come. lol

Who works in miles for astronomy? ;)
I always remeber it is about 8 light minutes away so hmmmm thats about
480 seconds so 3x10^8 meters/second gives us
4.8 x 3x10^10 meters = 14.4x10^10 meters = 1.44x10^11meters which equals (using gogle calc) 89 477 451.7 miles
so I guess 93 million
OMGZ You actually did the math...

You my friend are a true GEEK... You Rule
thanks :)

It sounds like you went further along studying astronomy then I ever did in college!
• steve Alpha 2009/08/22 02:01:25
thanks, dimensional analysis in physics
• Xuthus steve 2009/09/13 23:35:00
0.00001585 light years.
If anyone cares
• steve Xuthus 2009/09/14 00:01:58
very nice
• Xuthus steve 2009/09/14 00:32:19
Thank you, Steve.
• steve Xuthus 2009/09/14 15:59:30
now give it in swallow flight time ;)
• Xuthus steve 2009/09/14 22:42:39
African or European Swallow?
• steve Xuthus 2009/09/15 00:20:03
Clearly the african is the only swallow capable of interstellar flight
• Decahedron~~The Frozen Flame ♂ 2009/01/29 04:19:02
None of the above
Approximately - 93 million miles but it changes because the earths orbit is not perfectly round.
• Dave Sawyer ♥ Child of God ♥ 2009/01/29 04:12:36
93 million miles
But the picture is of Neptune, and the the distance varies about a million miles either way, being closest in January and farthest in July.
• Alpha Dave Sa... 2009/08/21 19:53:49 (edited)
"on average". The picture was used to trick people, but you got it right.

Depends on the time of year I think, but give or take...

93 million miles...and not a Starbucks between here and there...yet.

One astronomical unit!
• Dave Sa... Narcole... 2009/01/29 04:13:29
On average.

That is a Beautifully perfect Smart assed Answer...

True, but completely accurate! lol!!!

When I was a kid that was in a comercial, 93 million miles away. I don't remember what they were selling, I think it was Wonder Bread!

It's a good question honestly. I find one of the big things that people miss about astronomy is the sheer distances involved.
• NickNam... Icedrag... 2009/01/29 01:47:56
yep...it's hard to even imagine them. AU's are tiny on a galactic scale. And what really blows me away is how much empty space is in between everything. It's almost depressing...lol.
• Reborn NickNam... 2009/04/05 07:00:08
Have you seen the scale demonstration of the solar system done on a football field?
• NickNam... Reborn 2009/04/05 07:15:51
Not on a football field, but on a trail that ran by the astronomy building where I went to undergrad. There's also an interesting set of signs in DC outside the museums that has the scale of the planets and the distances.
• Reborn NickNam... 2009/04/05 07:19:57
The one I saw was done on a football field. The sun was on the goal line. (to shorten the story) the earth was on the 3 yard line.

The Kuiper belt was outside of the stadium, across the street and scattered into the surrounding block. The Ort cloud was WAY outside of that.

On the Universal scale, this is a miniscule distance, but on the human scale a lifetime wouldn't be enough to travel the radius.
• NickNam... Reborn 2009/04/05 07:23:55
What's interesting is that most people think everything in between is just empty space. It turns out most scientists today think the space isn't so empty afterall.
• Reborn NickNam... 2009/04/05 14:13:33
I know. I'm studying cosmology.

What's your postdoc on? Is astronomy a hobby or something more? Good to know, as an aside, that we have this to agree on completely.
• NickNam... Reborn 2009/04/05 20:02:22
Astronomy is just a hobby. I'm actually studying to be a vamp...er...I mean attorney. And by all means if you have any good lawyer jokes, feel free to share.
• Reborn NickNam... 2009/04/06 07:01:04
I got too many friends that are lawyers. They're not all bad.

I was about to get my JD, but got completely disenchanted with the manipulation the system encourages and tolerates.
• NickNam... Reborn 2009/04/06 16:02:46
Not going to argue with you there. Sometimes I get that salmon swimming upstream feeling.

There is a lot wrong with our legal system.

On the other hand, it's probably something along the same lines as our system of our government overall, it's the worst system out there aside from every other system that actually exists (not to borrow from Churchill without giving him credit).
• Reborn NickNam... 2009/04/07 05:30:38
Yeah, I get the salmon analogy. Further, the salmon ends up being a bear turd in the end. Not much to look forward to, is there?

It has its flaws, but it has its good points too. An all inclusive government is an elusive beast.
